三维激光扫描与无人机摄影在异形建筑三维建模中的应用

Application of 3D Laser Scanning and UAV Photography in 3D Modeling of Irregular Buildings

当前,三维激光扫描是异形建筑中首选的三维建模测量方式。但在实际异形建筑三维建模过程中,三维激光扫描会受到视角等多方面的限制,存在模型缺失等问题。相较于三维激光扫描,无人机倾斜摄影技术模型完整性较强,但整体精度较差,为大幅提升异形建筑三维建模精度,文章将两种测量建模技术相融合。以“鸟巢”为典型异形建筑样例,通过数据采集与分析,对单独建模和融合建模的精度展开研究,以期为异形建筑三维建模提供新方法、新思路。

At present,3D laser scanning is the preferred 3D modeling and measurement method for irregular buildings.However,in the actual 3D modeling process of irregular buildings,3D laser scanning is limited by various aspects such as perspective,and there are problems such as model missing.Compared to 3D laser scanning,UAV tilt photography technology has stronger model integrity,but overall accuracy is poor.To significantly improve the accuracy of 3D modeling of irregular buildings,this paper integrates the two measurement and modeling technologies.Taking the“Bird's Nest”as a typical example of irregular buildings,through data collection and analysis,the accuracy of individual and integrated modeling is studied,in order to provide new methods and ideas for 3D modeling of irregular buildings.
